DETAILED DESCRIPTION

The present disclosure will be described in detail below in combination with the accompanying drawings. The described embodiments are merely exemplary embodiments, rather than all embodiments consistent with the present disclosure. Based on the embodiments of the present disclosure, all other embodiments derived by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

FIG. 1 is a flow chart of a method for reducing temperature for UE in accordance with an exemplary embodiment of the present disclosure. The method may be performed by a target base station. As shown in FIG. 1, the method may include the following steps.

In step S101, a handover request sent by a source base station is received. The handover request carries at least one of configuration information expected by target UE and indication information indicating that the target UE overheats.

After the source station receives a measurement signal reported by the target UE, the handover request is sent to a target base station if it is determined that the target UE requires handover of the base station.

In this embodiment, before execution of step S101, the source base station may interact with other base stations available for handover to inform the other base stations whether it has the ability to reduce temperature for the UE by updating the configuration information. For example, when a base station sets up an X2 interface (namely, an interface between the base stations), capability information indicating whether the base station can reduce temperature for the UE by updating the configuration information or not may be carried in an X2 interface setup request and an X2 interface setup response.

Supposing that the source base station has the ability to reduce temperature for the UE, the source base station can choose a base station that has the ability to reduce temperature for the UE from other base stations available for handover as the target base station. In addition, after it is determined that both of the base stations have the ability to reduce temperature for the UE, the handover request sent by the source base station may carry at least one of the configuration information expected by the target UE and the indication information indicating that the target UE overheats. If the source base station, but not the target base station, has the ability to reduce temperature for the UE, the handover request sent by the source station does not carry at least one of the configuration information expected by the target UE and the indication information indicating that the target UE overheats.

Overheating of the target UE may present in various forms, including but not limited to the temperature of the UE being higher than a preset temperature, the temperature of the UE being higher than the preset temperature and lasting for a period of time, etc.

In step S102, first configuration information is sent to the target UE based on the handover request. The first configuration information is configured for the target UE to update its own radio communication parameter configuration so as to reduce its own temperature. The first configuration information may be the same as or different from the configuration information expected by the target UE.

If the handover request carries the configuration information expected by the target UE, the target base station can send the first configuration information to the target UE after receiving the handover request. The first configuration information may be the configuration information expected by the target UE and may also be new configuration information generated by the target base station with reference to the configuration information expected by the target UE, i.e., the first configuration information is different from the configuration information expected by the target UE. The target UE can update its own radio communication parameter configuration and reduce its own temperature after receiving the first configuration information. Thus, such problems as service interruption or UE restart caused by overheating of the UE may be avoided.

If the handover request only carries the indication information indicating that the target UE overheats, the target base station may send the first configuration information to the target UE after receiving the handover request. The radio communication parameter configuration identified by the first configuration information is lower than the radio communication parameter configuration obtained before the target UE receives the first configuration information. In this way, the temperature of the target UE can be reduced after the target UE updates its own radio communication parameter configuration based on the received first configuration information. Thus, such problems as service interruption or UE restart caused by overheating of the UE may be avoided.

In the foregoing embodiment, the handover request sent by the source base station is received, and the first configuration information is sent to the target UE based on information carried in the handover request, such that the temperature of the target UE can be reduced after the target UE updates its own radio communication parameter configuration based on the first configuration information. Thus, problems caused by overheating of the UE may be avoided.

FIG. 2 is a flow chart of a method for reducing temperature for UE in accordance with an exemplary embodiment of the present disclosure. As shown in FIG. 2, before the step S101, the method may further include the following steps.

In step S201, an X2 interface setup request sent by a source base station is received. The X2 interface setup request carries capability information indicating that the source base station is capable of reducing temperature for the UE by updating configuration information.

In this embodiment, the source base station can send the X2 interface setup request to a target base station. The X2 interface setup request carries the capability information indicating that the source base station is capable of reducing temperature for the UE by updating the configuration information.

In step S202, an X2 interface setup response is returned to the source base station to complete setup of the X2 interface. The X2 interface setup response carries capability information indicating that a target base station is capable of reducing temperature for the UE by updating the configuration information.

After receiving the X2 interface setup request, the target base station extracts the capability information indicating that the source base station is capable of reducing temperature for the UE by updating the configuration information from the received X2 interface setup request and returns the X2 interface setup response to the source base station. The X2 interface setup response carries the capability information indicating that the target base station is capable of reducing temperature for the UE by updating the configuration information. So far, both of the source base station and the target base station can learn about whether the other party has the ability to reduce temperature for the UE by updating the configuration information.

In the foregoing embodiment, the X2 interface setup request sent by the source base station is received to learn about that the source base station has the ability to reduce temperature for the UE by updating the configuration information based on the capability information carried in the X2 interface setup request. Meanwhile, the X2 interface setup response is returned to the source base station, such that the source base station can learn about that the target base station has the ability to reduce temperature for the UE by updating the configuration information based on the capability information carried in the X2 interface setup response. Thus, a condition is provided for subsequently transmitting the first configuration information to the target UE so as to reduce temperature for the target UE.

FIG. 3 is a flow chart of a method for reducing temperature for UE in accordance with an exemplary embodiment. The method may be performed by interaction among a source base station, a target base station and a target UE. As shown in FIG. 3, the method may include the following steps.

In step S301, a source base station sends an X2 interface setup request to a target base station. The X2 interface setup request carries capability information indicating that the source base station is capable of reduce temperature for the UE by updating configuration information.

In step S302, after receiving the X2 interface setup request, the target base station resolves the capability information indicating that the source base station is capable of reduce temperature for the UE by updating the configuration information from the X2 interface setup request, and returns an X2 interface setup response to the source base station to complete setup of the X2 interface. The X2 interface setup response carries capability information indicating that a target base station is capable of reduce temperature for the UE by updating configuration information.

In step S303, the source base station sends a handover request to the target base station through the X2 interface. The handover request carries at least one of configuration information expected by the target UE and indication information indicating that the target UE overheats.

During handover of the overheated target UE, the source base station may send information reported by the overheated target UE to the target base station through the X2 interface. The information reported by the overheated target UE may include but not limited to at least one of the configuration information expected by the target UE and the indication information indicating that the target UE overheats.

In step S304, the target base station sends first configuration information to the target UE based on the handover request.

If the target base station supports and agrees that overheating of the target UE may be solved by updating the configuration after receiving a handover request acknowledge message, the first configuration information may be sent to the target UE.

In step S305, the target base station returns the handover request acknowledge message that carries the first configuration information to the source base station.

After sending the first configuration information to the target UE, the target base station may inform the source base station of the configuration by the target base station to the overheated target UE through the handover request acknowledge message.

In step S306, the target UE updates its own radio communication parameter configuration based on the first configuration information to reduce its own temperature.

In step S307, the target UE sends a radio resource control (RRC) message to the target base station if it is detected that the target UE does not overheat. The RRC message carries identification information indicating that the target UE does not overheat.

After the problem of overheating is solved, the target UE may send the identification information indicating that the target UE does not overheat to the target base station through the RRC message to inform the target base station that the problem of overheating is solved.

In the foregoing embodiment, through interaction among the source base station, the target base station and the target UE, the overheated target UE may update its own radio communication parameter configuration based on the first configuration information sent by the target base station. Thus, the target UE may not overheat immediately after the handover is completed.

FIG. 4 is a flow chart of a method for reducing temperature for UE in accordance with an exemplary embodiment of the present disclosure. The method may be performed by the UE. As shown in FIG. 4, the method may include the following steps.

In step S401, first configuration information sent by a target base station is received.

The target base station may send the first configuration information to target UE based on information carried in a handover request after receiving the handover request sent by a source base station.

In step S402, radio communication parameter configuration of the UE is updated based on the first configuration information to reduce temperature for the UE.

The target UE may update its own radio communication parameter configuration and reduce its own temperature after receiving the first configuration information. Thus, such problems as service interruption or UE restart caused by overheating of the UE may be avoided.

In the foregoing embodiment, the first configuration information sent by the target base station is received, and the radio communication parameter configuration of the UE is updated based on the first configuration information to reduce temperature for the UE, such that problems caused by overheating of the UE may be avoided.

In step S400, if it is detected that UE overheats, at least one of configuration information expected by the UE and identification information indicating that the UE overheats is sent to a source base station in communication connection with a target base station.

Overheating of the target UE may present in various forms. For example, the temperature of the UE is higher than a preset temperature, or the temperature of the UE is higher than the preset temperature and lasts for a period of time.

In the embodiment, after it is detected that the UE overheats, at least one of the configuration information expected by the UE and the identification information indicating that the UE overheats may be sent to the source base station, such that when the source base station sends the handover request to the target base station, a handover request may carry at least one of the configuration information expected by the UE and identification information indicating that the UE overheats.
